Kerry Katona only married her ex-husband Mark Croft because she wanted free drugs.

The former addict eloped to Gretna Green with the ex-cabbie in 2007 following her bitter split from Brian McFadden, 38.

And she's now sensationally claimed she only got with the convicted drug dealer because she thought she'd be in for some perks.

“My second husband, with him being my mum’s dealer, I only married him because I thought I was going to get the drugs for free," she claimed as she opened a new rehab facility in Gloucester on Thursday. Mark has always denied supplying her with drugs.

However, Kez, 37 - who says her addictions started when her mum gave her speed aged just 14 - insisted what she really wanted was for him to stop her using drugs.

“Not that I wanted to take the drugs. I was taking it more and more because I wanted him to stop me and show that he loved me but it didn’t work out, he had me where he wanted," she added.

During their brief three-year marriage, the couple had children Heidi and Maxwell. However Kerry later claimed their time together was shrouded in a haze of drugs.

“Some weeks I was spending £500 a week on cocaine, which is quite a lot considering Mark was my dealer so I was getting in cheap,” she claimed to The Mirror just after their split in 2012.

“The lowest point for me was in my bathroom in Wilmslow with blood coming from my nose and a razor in my hand, wanting to cut myself but not having the courage to do it. I had so many fits on coke my nose would bleed. I wouldn’t have a bath for days.

"I had no friends, no family around. I was on so much medication, so many drugs. I wanted to die. I was that close to killing myself.”

At the height of her addiction, the desperate star tried to get clean at a rehab facility in Arizona.

“I even went to Arizona. It cost me £35,000 for six weeks,” she said. “But I got straight back on the coke. I was in and out of the Priory but again straight back on the coke.”

She finally turned a corner in 2010 after completing a stint at boot camp.

“I got away from Mark. I lost weight, felt so much better. It was like coming out of a coma. I felt a huge sense of achievement,” she said

“I had to go home to Mark but I kept it up, drinking herbal teas, eating fish, veg, I kept training too. I was clean and started thinking where has my money gone Mark? He didn’t like it.

“Five days after I got home he said, ‘do you want a line’ (of cocaine). I thought you b******. I kicked him out there and then. I felt great again.”

Croft went on to receive a two-year suspended jail sentence in 2015 after pleading guilty to running a £50,000 cannabis farm in his loft and blaming it on the loss of his 'lavish' lifestyle with Kerry.
